Quick Answer
The most effective way to make your teeth white depends on the type of staining you have. Over-the-counter products like whitening toothpastes and strips can remove minor, recent surface stains from food and drinks. For deeper, long-standing discoloration, professional whitening supervised by a dentist provides safer, more dramatic, and longer-lasting results.
Your Guide to a Whiter, Brighter Smile
If you feel self-conscious about the color of your teeth, you're not alone. Many people wonder how to make their teeth white and what the best options are. The answer depends on what caused the discoloration in the first place, and a professional evaluation is the first step toward a personalized treatment plan that delivers results you can trust.
Understanding What Causes Tooth Discoloration
Not all tooth discoloration is the same. The cause directly influences the best way to treat it. Stains fall into two main categories.
Stains on the Surface (Extrinsic)
Extrinsic stains are the most common type, developing on the outer layer of your enamel. These surface-level stains are caused by pigments from coffee, tea, red wine, and tobacco that cling to your teeth over time. The good news is these are often the easiest to remove.
Stains from Within (Intrinsic)
Intrinsic stains occur deep inside the tooth, in the layer called dentin. This type of discoloration can be caused by the natural aging process, certain medications, or trauma to a tooth. Because these stains are internal, they do not respond to surface whitening products.

Figuring out which type of staining you have is the critical first step. An evaluation with our team in Glendale, AZ can pinpoint the cause of your discoloration and set you on the right path.
How to Make Your Teeth White With Professional Treatment
When you want a significant and reliable change, it’s time to consider professional whitening. Treatments supervised by a dentist use more powerful whitening agents to achieve noticeable, long-lasting results that over-the-counter products cannot match. At Beyond Dental Care, we offer two excellent professional whitening options.
In-Office Whitening
In-office whitening is the fastest way to lighten your teeth by several shades in a single appointment. This option is ideal if you want to see immediate, impressive results for a special event or simply prefer not to wait.
Custom Take-Home Trays
For those who prefer to whiten on their own schedule, we provide custom-fit take-home trays. We create these from precise molds of your teeth, ensuring the professional-strength whitening gel is applied evenly and kept away from sensitive gum tissue.

Professional vs. At-Home Whitening: What's the Real Difference?
The number of whitening options can be overwhelming. Understanding the key differences between professional and at-home treatments helps you make the right choice for your smile.

The primary difference lies in the strength of the whitening agent and the supervision provided. Professional treatments use higher-concentration gels and are customized to your teeth, ensuring a safe and uniform result. You can explore how hydrogen peroxide safely whitens teeth in our detailed guide.
Here is a straightforward comparison.
| Feature | Professional Whitening (In-Office & Take-Home) | Over-the-Counter (Strips, Generic Trays) |
|---|---|---|
| Effectiveness | High-concentration gels lift deep intrinsic and extrinsic stains for dramatic, uniform results. Can brighten teeth by 5-10 shades. | Low-concentration gels primarily address minor, surface-level extrinsic stains. Results are often subtle and uneven. |
| Supervision | Directly supervised by a dental professional who assesses your candidacy and monitors for sensitivity. | Unsupervised. Relies entirely on following box instructions, with a higher risk of user error. |
| Customization | Trays are custom-molded to your teeth for a perfect fit, ensuring even gel application and protecting gums. | One-size-fits-all strips or generic trays that often fit poorly, leading to splotchy results and gum irritation. |
| Safety | Gum barriers are used in-office, and custom trays prevent gel from leaking onto sensitive gum tissue. | Gel can easily contact and irritate gums. Overuse can lead to significant tooth sensitivity and enamel damage. |
| Speed of Results | In-office treatments provide dramatic results in a single 1-hour visit. Take-home trays show significant results in 1-2 weeks. | Requires consistent use over several weeks or months to see noticeable, though often minimal, changes. |
| Long-Term Value | A higher initial investment, but provides superior, longer-lasting results and professional oversight. | A lower upfront cost, but results are temporary and may require frequent repurchasing for maintenance. |
While over-the-counter kits are accessible, they cannot match the safety, speed, or transformative power of a professional whitening treatment.
What Whitening Cannot Fix
It is important to know that teeth whitening treatments only work on natural tooth enamel. Any existing dental work—like crowns, fillings, bridges, or veneers—will not lighten along with your natural teeth.
If you have restorations on your front teeth, whitening can create a color mismatch. This is a common concern, particularly for senior patients with older restorative work. A personalized treatment plan may involve whitening your natural teeth first, then replacing old dental work with new restorations matched to your brighter shade.
You can learn more about how whitening, bonding, and veneers solve different smile problems to see which approach is right for you.
How to Maintain Your Bright Smile After Treatment
After whitening, your enamel is temporarily more porous and susceptible to staining for about 72 hours. To protect your results, it's best to avoid coffee, red wine, dark teas, and rich sauces during this time.

Using a straw for colored beverages can also help minimize contact with your front teeth. Of course, the foundation of a lasting bright smile is excellent oral hygiene and regular professional cleanings. We've laid out more aftercare advice in our guide on what to do after professional teeth whitening.
Frequently Asked Questions About Teeth Whitening
Here are some of the most common questions we hear from patients in our Glendale office about professional teeth whitening.
Will teeth whitening make my teeth sensitive?
Some patients experience temporary tooth sensitivity after whitening, which is normal and typically fades within 48 hours. Using a desensitizing toothpaste before and after your treatment can help minimize this sensation.
How long will my teeth whitening results last?
Results can last from several months up to a few years, depending on your diet and oral hygiene habits. If you regularly consume staining foods and drinks like coffee or tea, you may need touch-ups sooner. Regular professional cleanings are essential for maintenance.
Is professional whitening safe for my enamel?
Yes. When performed under the supervision of a dental professional, teeth whitening is a safe and effective procedure. We use proven materials and precise techniques to protect your enamel and gums while lifting stains.
Can I whiten my teeth if I have crowns or fillings?
Whitening agents only work on natural tooth enamel and will not change the color of dental restorations like crowns, veneers, or fillings. We always conduct a thorough evaluation to ensure your final result is seamless and uniform.
Who is a good candidate for teeth whitening?
The best candidates are adults and teens with healthy teeth and gums who want to correct extrinsic stains from food, drinks, or aging. A consultation is necessary to confirm your gums are healthy and that your type of discoloration will respond well to treatment.
To find out if professional treatment is the right way for you to make your teeth white, schedule a consultation with Dr. Lazore. We can create a personalized plan to help you achieve the bright, confident smile you deserve.
